x=7
Step-by-step explanation:
Answer:
x = 7
Step-by-step explanation:
Given
2x + 2 = x + 9 ( subtract x from both sides )
x + 2 = 9 ( subtract 2 from both sides )
x = 7
A man invests 10000 for 3 years at a certain rate of interest, compounded annually. At the
end of one year, it amounts to 11200. Calculate :
(i) the rate of interest per annum;
(ii) the interest accrued in the second year;
(ii) the amount at the end of the third year.
Step-by-step explanation:
10000, After 1 year amount = 11200 so interest after 1 year = 1200
Amount = P(1+R/100)T
11200 = 10000(1+R/100)1
R = 12%
Interest for the second year = 11200(1+12/100)1 - 11200 = 1344
after 3 years = 10000(1+12/100)3 = 14049.28
Step-by-step explanation:
(I) Principle = Rs 10000, After 1 year amount
= Rs 11200 so interest after 1 year
= Rs 1200
R = 12%
Amount = P(1+R/100)T
11200 = 10000(1+R/100)1
R = 12%——————————————————————————————————————
(Ii)Interest for second year = 11200(1+12/100)1 - 11200 = Rs 1344
(iii)Amount after 3 year = 10000(1+12/100)3 = Rs 14049.28

An electrician bought 120 feet of electrical wire and used 105 feet of it
What percent of the wire went unused?
A 15%
B 12.5%
C 8.75%
D 7%
Answer:
B. 12.5%
Step-by-step explanation:
Find how much was unused:
120 - 105
= 15
To find what percent this is, divide it by 120:
15/120
= 0.125
Multiply this by 100:
0.125(100)
= 12.5
So, 12.5% of the wire went unused
The correct answer is B. 12.5%

The camping trip costs $165. How long will it take you to save enough money?
25 Points I guess.
Answer:
11 weeks
Step-by-step explanation:
$165 / 15 = 11 weeks
11 weeks
Hope that helps!
The equation of line is given by y = 15x and the number of weeks to save enough money is 11 weeks
What is an Equation of a line?The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the number of weeks be x
Let the cost of trip be y
Let the equation of line be represented as A
Now , the value of A is
Let the first point be P ( 4 , 60 )
Let the second point be Q ( 8 , 120 )
Now , the slope of the line between the two points is
Slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Substituting the values in the equation , we get
Slope m = ( 120 - 60 ) / ( 8 - 4 )
On simplifying the equation , we get
Slope m = 60 / 4
Slope m = 15
Now , the equation of line is y - y₁ = m ( x - x₁ )
Substituting the values in the equation , we get
y - 60 = 15 ( x - 4 )
On simplifying the equation , we get
y - 60 = 15x - 60
Adding 60 on both sides of the equation , we get
y = 15x
Now , the cost of the camping trip is $ 165
Substitute the value of y = 165 , we get
165 = 15x
Divide by 15 on both sides of the equation , we get
x = 165/15
x = 11 weeks
Therefore , the value of x is 11 weeks
Hence , the equation is y = 15x

What is the sum of 4 and its additive inverse?

The additive inverse is the opposite sign quantity so the sum of 4 and its additive inverse will be 0.
What is summation?A summation, also abbreviated as a sum, is the outcome of adding two or more numbers or quantities. Here are always an integer number of terms in a summation.
Given the number 4.
The sign of the number 4 is positive.
An additive inverse is a number whose sign is opposite to the number.
For example, the additive inverse of -5 is 5, and 5 is -5.
So additive inverse of 4 will be -4.
Now sum of 4 and -4
4 + (-4) = 0
Hence "The additive inverse is the opposite sign quantity so the sum of 4 and its additive inverse will be 0".

Jane and 3 friends decided to split the cost of a pizza evenly. The total cost was $25.48. How much does each friend have to pay?
Answer:
$6.37
Step-by-step explanation:
Jane and 3 friends = Jane + another 3 people
= 4 people in total
Total Cost of pizza = $25.48
If 4 people split $25.48 evenly,
Amount each friend has to pay = Total Cost of pizza/Total number of people
= $25.48/4
= $6.37 per friend
Each friend has to pay $6.37 each if $25.48 is splitted evenly amongst them
